According to TSA regulations, you can pack slime in both your carry-on and checked bags, but your container of slime must not exceed 3.4oz/100ml if packed in your carry-on.
The TSA have a rule called the 3-1-1 rule that prohibits passengers from packing any liquid, gel, or aerosol in containers that exceed 3.4oz/100ml in their carry-on.
You might be thinking: that’s good to know, but surely that doesn’t apply to slime.
Well, in fact, slime is considered a liquid (a non-Newtonian fluid if we’re getting technical) by the TSA, so the 3-1-1 rule applies.
Packing Slime in Your Checked Bag
Fortunately, the 3-1-1 rule doesn’t apply to any liquids, gels, or aerosols packed in your checked bag.
So, you can pack slime in the bag you check in with your airline with no quantity restrictions, according to TSA checked bags regulations.
TSA Approved Slime
As you now know, slime is considered to be a liquid by the TSA, so to bring slime in your carry-on, it has to be in suitable containers.
You can either buy a bunch of small containers and place the slime in each one, or you can just buy a set of slimes in TSA-friendly containers, such as this one.
Bringing Slime on International Flights
The 3-1-1 rule is a global rule, even though it might not be called that worldwide.
In other words, you can bring slime on international flights in your checked bags with no limits, though if packed in your carry-on, each container of slime must be no greater than 3.4oz/100ml.
Note that this applies to when you’re traveling from the U.S., back to the U.S., and between other foreign countries.
You might also want to note that Norway, Jordan, and the United Arab Emirates have banned a select few slime brands, though it’s unlikely anything will happen if you fly to these countries with slime in your carry-on or checked bag.
At worse, the slime will be confiscated.
How to Pack Slime When Flying
Despite its purpose, slime is treated the same way as your toiletries, which means that you should pack it in the following way:
Make sure that the slime is in a container(s) no larger than 3.4oz/100ml.
Place the containers inside your liquids bag.
Your liquids bag should be clear, resealable and no larger than 32 ounces.
Take your liquids bag out and place it in a security bin when going through the airport screening process.
Other Toys You Can’t Bring
You can bring must popular toys on a plane including fidget spinners, stacking cups, and magnetic toys, but a select few toys are banned.
According to the TSA, toys like nerf guns, toy swords, and any other toys that resemble realistic firearms or weapons won’t be allowed in your carry-on.
